Did a little work on the car over the past week and made some more, albeit slow, progress... but, today it was "one step forward, two steps back"... which I'll elaborate on a little further down this update.
My friend Steve came over and our primary goal was to move the inter-cooler radiator up, so the euro M5 valance could be attached to the euro front apron that was on the car and hide that radiator (you may recall that the front apron had been modified with a bigger center opening to accommodate the small inter-cooler radiator, when it was up at VSR for body & paint work)
So, here's a summary of the work done this week (mostly today) and the problems encountered:
- secured small washer tank to inside of fender, under hood
- installed extra brake lights and brighter lamps in the taillights assemblies
- dyed front seat backs to match Beige color on rest of interior, e.g., seats
- installed trunk carpet pieces and removed antenna to replace it was a chrome one (had a shadowline one there originally)
- installed stock sound padding under parcel shelf and rear seat area
- installed rear seat belts
- installed back of rear seat (still have some speaker wires to connect to cross-overs, so holding off on seat bottom for a while)
- removed inter-cooler radiator, and Steve fabricated some brackets with 1" x 1/8"th aluminum flat stock and we moved it up a couple inches, so the M5 valance could fit over and hide the radiator (but still allow for adequate airflow for cooling). Thank God for rivnuts!

This took a while and was a lot of trail and error with the brackets, also moving or removing some things that were in the way, but, we were able to move it up and secure everything properly
- measured and marked where the holes needed to be drilled in the front apron, so the studs that are integrated in the valance would line up and allow for proper fitment & mounting.
- attempted to install the valance to the apron... it wouldn't fit right... it looks to be about 1/2" or so to small overall!!

When we put the studs that are at the two ends of the valance (near the front of the wheels) into the holes we had drilled in the apron, the center of the valance was pulled so tight it didn't line up with the crease on the apron, but rather was under it and wavy in the center!! We also had to drill a couple of new holes in the apron for the studs that were further in-board on the valance (about a third of the way from each end), as they didn't line up as they should have from our initial markings. We then removed the valance from my M5 and tried this new euro M5 valance on it... it was snug, but it fit just fine. Now we are really confused!!
Here's some background on the euro apron and valance. When I bought the car, it came with all new parts for the euro bumper conversion, including the euro metal apron, that the PO was planning to have installed. When we installed the custom larger, single inter-cooler radiator (rather that two small one that were initially in the Stage II Turbo kit from TCD), it therefore required that the euro front apron be slightly modified with a larger opening in the center (the sheet metal was cut to make room for the radiator as it was initially installed,and then it was prepped, painted, and installed on the car). When I picked the car up at VSR after painting, I noticed the apron didn't have any openings where the tow hooks are located, and the small squares on the top center of the apron, under the front grill, were solid and not cut out like on my M5's apron??? I called Chris Kohler

and he informed me that BMW made a "cab" version of that apron that got installed on certain e28s... it didn't have the tow-hook openings or the cut-outs on the top, but, it was otherwise the same (I later found out that this valance also didn't have the holes pre-drilled for attachment of a valance). I surmise that this is the apron the PO got either by mistake or was all that was available in stock??
Anyway, since I was then looking for a way to hide this radiator, as it was now so prominent and visible, I figured a valance would do the job. And, after considering other after-market alternatives or some fabricated approach, I decided on the euro M5 valance, like the one on my M5 which has the exact same euro conversion. A few months back, when Steve and I were taking measurements of the valance that was on the my M5, to see how far up the radiator would have to be moved to allow a M5 valance to cover it, etc., we concluded it would do the job... and, I'd have the clean, simply look I was after. So, I ordered the M5 euro valance. When it came in didn't have the center cut-outs for air-flow (of the oil-cooler on the S38)??? We ordered another one (there were 3 available), it came in the same way! OK, I'll just have to go on the back side of the valance and Dremmel out those cut-outs, no problem.
So, today when the valance wouldn't fit on/over the apron (wasn't really close) we were/are perplexed?

We will try again in a couple weeks to solve this mystery... meanwhile, I'll be doing a little research and seeing if anyone has any thoughts on what the problem is? So far this evening I discovered, via the ETK, the following about the euro apron and the euro valance:
- the euro apron part # for the 535, the M5, the 524td, and the 528e are all identical (41 33 1 922 063)
- the euro apron part # for the 528i (061),the 533 (065) are different in the last 3 digits
- the "cab" option shows for the 528i, but it shows the same 063 part number for that apron as for the 535, M5, and 528 apron????? Huh????
I would think that the shape and size of any e28 euro apron would be identical, and the only difference would be with the "cut-outs" and/or "stud holes drilled"? At least for the 535, M5, and e28 ones?
As for the euro "valance"... the part numbers for the 535, the M5, and the 528i euro valances are all different, but the ETK pictures look identical and the tow covers, etc., are all the same #s?? Again, I'd guess that the shape and size of these valances are identical, just the center cut-out might be different??
So, I need to figure out why my euro valance doesn't fit on my euro apron... or what mix and match issue I have (I don't know what the part # was for the apron, as that was bought by the PO... but I do know the one I ordered for the M5 valance)? Anyway, we'll see what I learn and proceed accordingly... or it's "fab" time!
Here are some pics of the above referenced work.

This picture shows the radiator before we moved it up, note new M5 valance on ground, without center cut-outs

radiator moved up and installed...couple inches higher than in earlier picture

tape on apron with white markings where holes for valance studs are to be drilled

This is the valance we took off the M5... note center cut-outs for air flow to oil cooler

This is the new M5 valance I ordered and got form BMW. Note no center cut-outs for air flow
